16-T0174 Field inspection pocket vane tester

STANDARD: ASTM D2573

This tester, designed to measure the undrained shear strength (CU) of cohesive soils, consists of a cylindrical body with a torsional spring and three interchangeable vanes of different sizes used depending upon the expected strength of the soil.

The vanes have the following dimensions:

• small size 32x16 mm (height x dia.)
• medium size 40x20 mm (height x dia.)
• large size 50.8x25.4 mm (height x dia.).

The height/diameter ratio of all vanes is 2. During operation the vane is driven for 5-6 cm into the soil and then turned with the handle. Deep measures (i.e. on the top of undisturbed samples) can be obtained using the extension rod.

Specifications

• All stainless steel construction
• Vane dimensions (height x dia.): 32x16 – 40x20 – 50.8x25.4 mm
• Measuring range: 0 to 240 kPa (O-24 N/cm2)
• Torque value: 5 N·m
• Extension rod: included
• Overall dimensions (assembled): 310x105 mm

The tester is supplied in a plastic case.
